Struct `DateTime`

pub struct DateTime { /* private fields */ }

Representation of a moment in time.

Zip files use an old format from DOS to store timestamps, with its own set of peculiarities. For example, it has a resolution of 2 seconds!

A DateTime can be stored directly in a zipfile with FileOptions::last_modified_time, or read from one with ZipFile::last_modified.

Warning

Because there is no timezone associated with the DateTime, they should ideally only be used for user-facing descriptions.

Modern zip files store more precise timestamps; see crate::extra_fields::ExtendedTimestamp for details.

Implementations

`impl DateTime`

const DEFAULT: Self = _;

Constructs a default datetime of 1980-01-01 00:00:00.

fn default_for_write() -> Self

Returns the current time if possible, otherwise the default of 1980-01-01.

const unsafe fn from_msdos_unchecked(datepart: u16, timepart: u16) -> DateTime

Converts an msdos (u16, u16) pair to a DateTime object

Safety

The caller must ensure the date and time are valid.

fn try_from_msdos(datepart: u16, timepart: u16) -> Result<DateTime, DateTimeRangeError>

Converts an msdos (u16, u16) pair to a DateTime object if it represents a valid date and time.

fn from_date_and_time(year: u16, month: u8, day: u8, hour: u8, minute: u8, second: u8) -> Result<DateTime, DateTimeRangeError>

Constructs a DateTime from a specific date and time

The bounds are:

year: [1980, 2107]
month: [1, 12]
day: [1, 28..=31]
hour: [0, 23]
minute: [0, 59]
second: [0, 60] (rounded down to even and to [0, 58] due to ZIP format limitation)

fn is_valid(&self) -> bool

Indicates whether this date and time can be written to a zip archive.

const fn timepart(&self) -> u16

Gets the time portion of this datetime in the msdos representation

const fn datepart(&self) -> u16

Gets the date portion of this datetime in the msdos representation

const fn year(&self) -> u16

Get the year. There is no epoch, i.e. 2018 will be returned as 2018.

const fn month(&self) -> u8

Get the month, where 1 = january and 12 = december

Warning

When read from a zip file, this may not be a reasonable value

const fn day(&self) -> u8

Get the day

Warning

When read from a zip file, this may not be a reasonable value

const fn hour(&self) -> u8

Get the hour

Warning

When read from a zip file, this may not be a reasonable value

const fn minute(&self) -> u8

Get the minute

Warning

When read from a zip file, this may not be a reasonable value

const fn second(&self) -> u8

Get the second

Warning

When read from a zip file, this may not be a reasonable value
